What standards are generally used to produce high-quality sanitary butterfly valves

The production of high-quality sanitary butterfly valves usually follows a series of strict standards to ensure that their performance, quality, and hygiene requirements meet the industry's high standards. Here are some of the main production standards:

1. International and domestic standards

International standards: such as ISO (International Organization for Standardization), DIN (German Industrial Standards), IDF (International Dairy Federation), SMS (Sanitary Pipe Connection Standard), 3A (American 3A Sanitary Standard), etc. These standards provide detailed requirements for the material, structure, sealing, cleanliness, and other aspects of butterfly valves.

Domestic standards such as GB/T 2238-1989 (Valve Structure Length), GB/T 9113.1-2000 and GB/T 9115.1-2000 (Flange Connection Dimensions), GB/T 13927-1992 and JB/T 9092-1999 (Pressure Testing) also provide guidance for the production of sanitary butterfly valves.

2. Material requirements

High quality sanitary butterfly valves are usually made of stainless steel materials such as SUS304, SUS316L, etc., which have good corrosion resistance and sanitary performance. The valve body and sealing materials must comply with relevant hygiene standards to ensure that they do not cause contamination when in contact with media such as food, beverages, pharmaceuticals, etc.

3. Processing and surface treatment

Processing accuracy: Each component of the butterfly valve needs to be precision machined to ensure assembly accuracy and sealing performance.

Surface treatment: The inner and outer surfaces of the product usually need to be polished with polishing equipment to achieve surface precision requirements, with a bright and dust-free surface, no burrs or pricks, and to meet hygiene requirements.

4. Performance indicators

Sealing performance: High quality sanitary butterfly valves should have good sealing performance to ensure no leakage in the closed state.

Flow regulation: Butterfly valves should also have good flow regulation functions to meet the needs of different working conditions.

Service life: Through strict strength and sealing tests as well as fatigue life tests, the butterfly valve is ensured to have a long service life.

5. Scope of application

High quality sanitary butterfly valves are widely used in industries such as food, beverage, pharmaceuticals, dairy products, beer, and fine chemicals, which have high requirements for the sanitary performance, corrosion resistance, and service life of valves.

In summary, the production of high-quality sanitary butterfly valves follows a series of international and domestic standards, using high-quality stainless steel materials, precision machining and surface treatment, with good sealing, flow regulation function and long service life, to meet the high requirements of relevant industries for sanitary valves.
